The sun is our oldest light source and one of the most universal cues that we use to tell time. The changing quality and position of the sun in the sky guides our daily transitions from sleeping to waking and from daytime to nighttime activities. The sun also fine tunes our biological clock to synchronize with the daily cycle of lightness and darkness outside.

That's why Sunn was created, to improve the human condition by offering a way for indoor lighting to put people back in touch with the daily rhythm of the sun, the same sun we as humans have evolved with and for.
